Abstract
The invention discloses a high-temperature retarding and water reducing agent prepared by mixing the following raw materials in parts by weight: 35-45 parts of polycyclic aromatic hydrocarbon sulfonated formaldehyde condensates, 20-30 parts of acyclic hydroxyl sulfonate condensates, 10-15 parts of diethylenetriaminepenta(methylene-phosphonic acid), 8-16 parts of calcium saccharate, 12-18 parts of alunite powder, 5-10 parts of xanthan gum powder, 4-8 parts of barium metaborate, 3-6 parts of sodium lauryl sulfate, 2-4 parts of pentaerythrite di-n-stearate, 6-12 parts of maleic anhydride-styrene sulfoacid copolymers, 10-15 parts of blast furnace slag powder, 5-10 parts of waste saccharide slag powder, 7-13 parts of nekal and 4-7 parts of auxiliary. The water reducing agent disclosed by the invention is excellent in high temperature resistance, relatively wide in applicable temperature range (150-250 DEG C), capable of reducing cement hydration heat release, reducing the temperature stress of the concrete, avoiding generating temperature cracks and completely meeting the construction requirement for high-temperature and high-pressure well cementation, suitable for continuously pouring mass concrete under a high temperature condition, remarkable in water reducing enhancement effect, good in slump loss resistance and wide in market prospect.
Description
Technical field
The present invention relates to a kind of high temperature modification retardation water reducing agent, belong to concrete admixture field.
Background technology
Concrete admixture, is called for short admixture, refers to before mixing concrete mixing or in mix process, mixes to improve the material of concrete performance.Because admixture can improve concrete performance effectively, and have good economic benefit, be all widely used in many countries, the application in engineering more and more comes into one's own, and becomes material indispensable in concrete.Wherein retardation water reducing agent is the one in concrete admixture, and it can delay concrete coagulating time, makes the fresh concrete long period keep plasticity, convenient cast, improve operating efficiency, can not cause detrimentally affect to later concrete properties simultaneously, and have water-reduction concurrently.The retardation water reducing agent resistance to elevated temperatures deficiency that used in the market, cannot meet High Temperature High Pressure cementing operation needs.
Summary of the invention
To the object of the invention is the defect existing in prior art in order solving, a kind of high temperature modification retardation water reducing agent of resistance to elevated temperatures excellence to be provided, to meet the construction needs of High Temperature High Pressure well cementation.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of high temperature modification retardation water reducing agent, is mixed by the raw material of following weight part: polycyclic aromatic hydrocarbon sulfonate formaldehyde condensation products 35-45, aliphatic hydroxyl sulphonate condenses 20-30, diethylene triamine pentamethylene phosphonic 10-15, sugared calcium 8-16, alum stone flour 12-18, xanthan rubber powder 5-10, barium metaborate 4-8, sodium laurylsulfate 3-6, pentaerythritol stearic acid ester 2 2-4, maleic anhydride-styrene sulfonic acid copolymer 6-12, ground granulated blast furnace slag 10-15, useless sugared ground-slag 5-10, pull open powder 7-13, auxiliary agent 4-7;
Described auxiliary agent is made up of the raw material of following weight part: magnesia 10-15, Humic acid Magnesium 3-6, ammonium benzoate 2-4, α-sodium olefin sulfonate 6-12, myo-Inositol hexaphosphate 1.5-2.5, iso-butylene triethoxyl silane 3-5, poly-ferric chloride 5-10, germanite powder 12-18, titanium dioxide 5-10, myristyl glucoside 1-2, polyamide wax 4-6, lithium magnesium silicate 2-3, tea saponin 1.5-2.5;
